Using the TD Device to Access Screens and Alarms When you configure the TD device with the Text Display wizard of STEP 7-Micro/WIN, you create the screens and alarms for the TD device. You use the buttons on the keypad of the TD device to navigate through the screens and menus. The TD 200 device uses the standard TD keypad. The standard faceplates for the TD devices are shown in Figure 1-2.

The TD 100C and TD 200C allow you to create your own custom-designed buttons with specialized functions.



Figure 1-2 Standard Keypad Configuration for the TD Devices

Dividing Information into Screens and Bit-Enabled Alarms As shown in Figure 1-3, you can configure the TD device to display screens (which are initiated by operator action) and bit-enabled alarms (which are initiated by the S7-200 CPU).

Screens: You can create screens that allow the operator (using the TD device) to initiate the interaction with the S7-200 CPU. With the TD device, you can configure a user menu (up to 8 entries or groups for the TD 200C, TD 200, and TD400C, and up to 4 entries or groups for the TD 100C) that provides a hierarchy for the screens. You can create up to 8 screens for each menu item or group.

Alarms: You can create alarm messages that allow the user program in the S7-200 CPU to initiate interaction with the operator by displaying a message on the TD device.

During the configuration of the TD device, you also designate which type of message (screens or alarms) will be the default display mode for the TD device. After power-up, the TD device goes to the default display mode. Also, the TD device returns to the default display mode after a period of inactivity (if no buttons have been pressed for one minute).



Storing the Screens and Alarms in the Parameter Block The S7-200 CPU stores the text, embedded variables, and format information for the alarms and screens in a parameter block located in V memory. You use the Text Display wizard to configure the starting address for the parameter block in V memory, and the Text Display wizard allocates the memory required to store the information for the TD device.

If you configure more than one parameter block for the S7-200 CPU (with each parameter block having a different range of addresses in V memory), you can connect several TD devices to that one S7-200 CPU. You configure the V memory address for the specific parameter block for each of the TD devices. The Diagnostic Menu of the TD device provides a TD Setup command for specifying the starting address of the parameter block.

Tip The parameter block for the TD 100C and the TD400C is not compatible with other TD devices. The TD 100C parameter block is only compatible with a TD 100C parameter block, and the TD400C parameter block is only compatible with a TD400C parameter block.

Displaying the Screens and Alarms on the TD Device When the operator uses the buttons on the TD device to select a screen, the TD device reads the screen information from the parameter block (stored in V memory of the S7-200 CPU) and displays the appropriate screen.

When you configure an alarm, you also configure an alarm bit for enabling a specific alarm. The logic of your user program sets this alarm bit to display the alarm on the TD device. When you create the text for the alarm, you also designate the alarm bit. If you configured an alarm to require acknowledgement by an operator, that alarm also has an acknowledge bit. The TD device continuously polls the alarm bits to determine which alarms have been enabled.

To display an alarm on the TD device, your user program in the S7-200 CPU must first set the alarm bit for the specific alarm. When your user program sets one of the alarm bits, the TD device then reads the alarm bits in the parameter block in the S7-200 CPU and displays the corresponding alarm message.

Product Overview 1.7 Creating a Custom Faceplate for the TD Device


1.7 Creating a Custom Faceplate for the TD Device

Creating a Custom Faceplate for the TD Device With the TD device, you can design a custom faceplate that can be layered onto any background image. The TD 100C and the TD 200C lets you incorporate buttons (keys) of varying size, with varying shapes, colors or fonts. The TD400C lets you incorporate buttons (keys) of varying colors and fonts. The positions and size of the TD400C buttons (keys) are fixed.

As shown in Figure 1-7, you use several applications to create a custom faceplate:

Keypad Designer: Creates the layout and the configuration for the keypad

Third-party graphics application: Designs the graphical appearance of the faceplate

STEP 7-Micro/WIN (Text Display wizard): Configures the parameter block for the TD 100C, TD 200C, and the TD400C

Word-processing application (optional): Prints multiple copies of the faceplate Siemens provides document files (in 6 languages) for Microsoft Word that help you to align the panel images for the perforations on the A4 blank faceplate material. To open these documents, browse to the Templates subdirectory under the Keypad Designer application (C:/Program Files/Siemens/TD Keypad Designer/Templates) and select the template for your TD device and language.

Figure 1-8 Using the Keypad Designer and Other Applications to Create a Custom Faceplate

Product Overview 1.8 Printing the Custom Faceplate for the TD device


1.8 Printing the Custom Faceplate for the TD device

Printing the Custom Faceplate for the TD Device The TD 100C and the TD 200C ship with one blank faceplate (envelope-size) for printing the faceplate. The faceplate is constructed from durable, polyester material which has been designed especially for use on HMI faceplates.

The TD400C does not include a blank faceplate. You can either order blank faceplates, or use the Keypad Designer to print a TD400C custom faceplate on A4 paper and take it to a local supplier to make a custom TD400C faceplate.

You can print a single faceplate directly from the Keypad Designer on the envelope-sized blank faceplate.

To print multiple faceplates, you can use the Microsoft Word template (provided in the Templates subdirectory) that ensures your faceplate design is properly sized. You can print multiple faceplates onto the perforated A4-size blank faceplate sheets.

Refer to Chapter 3 for specific information about printing the custom faceplate for your TD device.

Tip: The faceplate material is specially treated on one side to accommodate printing with a laser printer. The treated surface is up (or toward you) when you are holding the material with the cut corner in the top right of the sheet.

Ensure that the material is correctly inserted into the laser printer so that the faceplate prints the reversed image onto the treated surface of the material. You must print a reversed-image version of the faceplate onto the faceplate material.

Before printing your custom faceplate onto the blank faceplate sheet, first test your design by printing the faceplate onto regular paper. You can then temporarily use the paper faceplate to test the functionality of the design with your TD device.

Printer Requirements To print your custom-designed image onto the blank faceplate material, you must use a laser printer that supports the following features:

Paper size: The laser printer must be able to print on both the A4 (210 mm X 297 mm) and envelope formats.

Color: The laser printer must support color printing.

Transparencies: The laser printer must support the printing of transparencies (or other non-paper stock)

Ordering Additional Faceplate Material You can order additional blank faceplates for the TD 100C, TD 200C, and TD400C device in perforated A4-size sheets (10 sheets/package). The faceplate material is especially designed for printing on a laser printer. The blank faceplate sheets also allow you to utilize the services of professional printing vendors that specialize in laser printing in order to create large quantities of high-quality faceplates.



Contact your local Siemens representative or distributor to purchase additional quantities of the faceplate material. The order numbers are shown below:

TD 200C: the order number for additional blank faceplates is 6ES7 272-1AF00-7AA0

2.6 Installing a Faceplate for the TD 100C, TD 200C and TD400C

Installing a Faceplate for the TD 100C, TD 200C, and TD400C The TD 100C and TD 200C ship with a blank faceplate (envelope size) for creating a custom-designed faceplate. The TD400C does not ship with a blank faceplate; you can order a package with blank faceplates (see appendix A for order information).

The TD devices do not ship with the faceplate attached. The front of the TD is an adhesive surface (shipped with a protective paper) that allows you to attach your custom faceplate.

Refer to Chapter 3 for information about designing and printing a custom faceplate.

The figure below shows the dimensions for the faceplate of the TD devices. Blank faceplate material for the TD 100C, TD 200C and TD400C is available in the sizes shown below.

Envelope size for printing a single faceplate (TD 100C, TD 200C only)

A4 size (210 mm x 297 mm) for printing multiple copies of the faceplate (TD 100C, TD 200C, and TD400C)

You must cut the faceplate from the envelope-sized material, but the A4 material is perforated to allow you to remove the faceplates without cutting.

Use the following procedure to install your custom faceplate on the TD device. The example shown here is for the TD 200C. Installing a faceplate on a TD 100C and TD400C is similar; the differences are noted below. To prepare for installation, remove the protective film covering the display window of the TD device and the back of the preprinted (standard) faceplate. The protective film is blue for the TD 100C and the TD 200C, and is transparent for the TD400C.

1. The dimensions for the custom faceplate are shown for the TD device.

2. If your TD device has a strip of protective paper, remove the strip to expose the strip of the adhesive. For the TD 200C and the TD400C, it is on the left side of the device. For the TD 100C, it is on the right side of the device.

3. Carefully align your custom faceplate on the entire TD device, and then seal the faceplate to the exposed adhesive by pressing down on the left (TD 200C and TD400C) or on the right (TD 100C) side of the faceplate.



4. Carefully lift back the unadhered faceplate and remove the rest of the protective paper from the TD device.

5. Carefully position the faceplate onto the TD device. Firmly press the faceplate onto the adhesive, taking care to remove any air bubbles that may have been trapped underneath.

NOTICE

Do not use excessive force when you install the faceplate onto the TD400C device.

Chapter 4 describes the Text Display wizard

2.7 Connecting the TD/CPU Cable

Connecting the TD/CPU Cable

NOTICE Operating the TD device with an ungrounded voltage source can damage the TD device.

The TD device may only be connected to grounded voltage sources. Non-grounded operation can cause the TD device to become damaged.

Always ensure that the voltage source for the TD device is properly grounded.

The TD devices can use the TD/CPU cable for communicating with the S7-200 CPU.

You can connect the TD device directly to the S7-200 CPU, creating a one-to-one network configuration. In this configuration, one TD device connects to one S7-200 CPU through the TD/CPU cable.

You can connect multiple TD devices to multiple S7-200 CPUs over a network. The TD device defaults to address 1 and attempts to communicate to a CPU at address 2.

For more information about connecting to multiple CPUs, see Appendix B. For information about changing the default addresses in the TD device, see Chapter 5.

If you require a longer cable (>2.5 m) to connect the TD device to the S7-200 CPU, use PROFIBUS components for the network connection. Refer to the SINEC IK10 Catalog.

Installing your Text Display (TD) Device 2.8 Supplying Power for the TD Device


2.8 Supplying Power for the TD Device

Supplying Power for the TD Device The S7-200 CPU uses the TD/CPU cable to provide power to the TD device. Use this type of power supply when the distance between the TD device and the S7-200 CPU is less than 2.5 m (the length of the TD/CPU cable). The TD 200, TD 200C and the TD400C have the option of using an external power supply.

Tip The TD 100C device must use the TD/CPU cable to provide power from the S7-200 CPU to the TD device. The TD 100C does not have the option of using an external power supply.

Tip If the distance between the TD 200, TD 200C or TD400C and the S7-200 CPU is greater than 2.5 m, use an external 24 VDC power supply.

If you require a longer cable (greater than 2.5 m) to connect the TD device to the S7-200 CPU, use PROFIBUS components for the network connection. Refer to the SINEC IK10 Catalog.

Refer to Appendix B for information about using the TD device on a network.

As shown in the figure below, the TD device provides up to two options for providing power:

The TD/CPU cable allows the S7-200 CPU to provide power to the TD device over the communications port. This is the only option available for the TD 100C.

For information about the TD/CPU cable and the communications port, refer to Appendix B.

You can connect the TD 200, TD 200C or the TD400C to an external power supply.

The TD 200, TD 200C or TD400C requires 120 mA at 24 VDC to operate. An optional power connector is provided with the TD 200, TD 200C and the TD400C.

Installing your Text Display (TD) Device 2.9 Establishing a Connection for Your TD Device


2.9 Establishing a Connection for Your TD Device

Establishing a Connection for Your TD Device As described in Chapter 4, you use the Text Display wizard of STEP 7-Micro/WIN to configure the screens, alarms, languages, and custom keypad layout for the TD 100C, TD 200C and the TD400C. The S7-200 CPU stores this information in a parameter block (V memory).

The TD devices ship with a default configuration and are set to communicate at a rate of 9600 baud. The TD devices must communicate with the S7-200 CPU to be able to read the parameter block.

You must configure your TD device to communicate at the same baud rate as your S7-200 CPU.

TD 100C, TD 200C, and TD400C Until the TD device successfully connects to the S7-200 CPU and reads the parameter block, the TD device remains configured for the standard TD keypad shown in the figure below.

To change the baud rate of your TD device, you use the ESC and ENTER buttons to navigate to the Diagnostic/TD Setup Menu and change the TD Setup parameters. (See Chapter 5.) Because the TD devices ship with no faceplate attached, it may be difficult to consistently press ESC or ENTER.

The TD 100C, TD 200C, and TD400C devices ship with a faceplate for the standard TD keypad. In addition, the Keypad Designer provides a sample faceplate for the standard TD keypad in the following directory.

C:/Program Files/Siemens/ TD Keypad Designer/Templates

For temporary use, you can print this faceplate onto paper and lay the paper on top of the TD device (without removing the covering from the adhesive).

Refer to Chapter 3 for information about opening the Keypad Designer and printing a faceplate.

Installing your Text Display (TD) Device 2.9 Establishing a Connection for Your TD Device


Figure 2-10 Standard TD Keypad for the TD 100C, TD 200C and TD400C

Tip On an initial setup for the TD 100C, TD 200C, or TD400C, use the default keypad template shipped with the device to configure baud rates and addresses. Once the TD device has communicated to the CPU, the TD device will use the custom keypad configuration.

3.4 Adding Buttons to the Keypad

Adding Buttons to the Keypad The TD 100C and the TD 200C allow you relative freedom when designing your keypad. With the TD400C, the position and size of the buttons are fixed. You cannot add, remove, or change the TD400C buttons.

On the TD keypad you can configure up to 20 buttons for the TD 200C, up to 14 buttons for the TD 100C, and up to 15 buttons for the TD400C.

You can vary the size and the location of the buttons (TD 100C and TD 200C only)

You can define the functionality for each button.

The Keypad Designer provides a grid that aligns the location of the buttons with the physical keypad of the TD device.

Figure 3-6 Adding the Button to the TD 100C and TD 200C Keypad

Tip Typically, your keypad design should always include buttons with the following functions: Enter, Escape, Up Arrow, and Down Arrow. These functions allow you to access the pre-configured menus and functions of the TD device.

Using the Keypad Designer to Create a Custom Faceplate for your Text Display (TD) Device 3.4 Adding Buttons to the Keypad


Inserting a Button With the TD 100C and the TD 200C, you can add a button to the keypad grid. The TD400C does not have this option.

1. Click the Draw Button icon.

2. Move the cursor over the grid.

3. Move the cursor (and button) into position on the keypad grid.

4. Hold down the left mouse button and drag the cursor to adjust the size and shape of the button.

5. Release the mouse button to insert the button onto the keypad

After you have inserted the button onto the keypad grid, you can relocate the button by dragging it to a new location on the grid. However, you cannot resize the button.

Figure 3-7 Adding a Button (TD 100C and TD 200C)

Modifying the Shape of a Button With the TD 100C and the TD 200C you can modify the shape of a button. The Keypad Designer provides two methods for modifying the shape of a button. The TD400C does not have this option.

Changing the size or shape of a button by adding a second button on top of the first button

Erasing a portion of the button

Extending the Shape of a Button You cannot resize a button that has been inserted onto the keypad grid. However, with the TD 100C and the TD 200C, you can insert a second button on top of the first button to create a new size for the button. The TD400C does not have this option.

As shown in the figure below, adding a second button also allows you to create buttons of non-rectangular shape (combining the shapes of both buttons).

When you insert the second button, ensure that the cursor is within the boundaries of the first button.

Figure 3-8 Extending the Shape of a Button (TD 100C and TD 200C)

Erasing an Area of the Button With the TD 100C and the TD 200C, you can change the shape of the button by clicking the Erase Button icon. The TD400C does not have this option.

As shown in the figure below, the Keypad Designer alerts you if the shape of the button is invalid.

To delete the entire button, select the button and press the Delete key.

Figure 3-9 Erasing an Area of a button (TD 100C and TD 200C)

Tip A valid button must consist of at least 4 adjacent cells, with each cell having at least 2 neighbor cells. A neighbor cell must be left, right, or up or down from the cell. Diagonal neighbor cells are not counted.

3.5 Defining the Properties of the Button

Defining the Properties of the Button After you create the button, you define the function that will be performed when an operator presses the button.

You use the Properties dialog to configure the functionality for the button:

Select the button to be configured.

Select the Edit > Properties menu command to display the Properties dialog.

You can also right-click the button and select Properties from the context menu. You can double-click the button to bring up the Set Button Properties.

Select the function for the button and provide a valid function name. Click OK. See Figure 3-10 for an example of the TD 200C button functions.



The TD400C has up to 15 buttons that can be defined. You do not have to define (or use) all the buttons. Some buttons can be blank or unused.

Table 3-2 describes the functions that you can configure for the button. The default function is to set a bit in the S7-200 CPU (Set PLC Bit).

Some functions can also be used in combination with other buttons, such as SHIFT or the arrow buttons. The Properties dialog provides suggestions for appropriate buttons for combining the functions.

After you configure the functions for each button on the keypad, select the File > Save or the File > Save As menu command to create the configuration file (*.td2 for the TD 200C, *.td1 for the TD 100C, or *.td4 for the TD400C).

Tip A button that has been configured will display the button name on the button in the panel layout.

3.6 Exporting the Keypad Layout to a Graphics Application

Exporting the Keypad Layout to a Graphics Application After you have configured the buttons on the keypad, you can create the graphical representation for the faceplate. You can use any third-party graphics application to add colors, lines and other artwork to the panel design.

The Keypad Designer exports the layout of the buttons as a bitmap file (*.bmp) that you edit with the graphics application.

As shown in the figure below, the button template provides a bitmap image of the layout of the keypad that you can use with your graphical application to position, size and align the graphical elements of your faceplate design. These elements can include logotype, text, or other images.

The Keypad Designer allows you to export the layout of the buttons into your graphics application. Use the File > Export >Button Template to File menu command to create a bitmap file (*.bmp) that you insert into the graphics application.

After you customize the layout (adding background image, colors, buttons or logotype), you save the file as a bitmap (*.bmp). This bitmap becomes the panel image for the Keypad Designer.

Figure 3-12 Creating the Panel Image: Export Button Layout

Using the Keypad Designer to Create a Custom Faceplate for your Text Display (TD) Device 3.7 Adding a Panel Image to the Faceplate


Tip When you design the colors for your panel image, be aware that any white area will be printed as transparent (clear).

Figure 3-13 Exporting the Button Template to a Graphics Application

3.7 Adding a Panel Image to the Faceplate

Adding a Panel Image to the Faceplate Using your own graphics application, you create the following graphical elements for the faceplate of the TD 100C, TD 200C, or the TD400C:

Button images

Background image or color scheme

Text (for the buttons or the background)

Logotypes (and other images or text)

For the TD 100C and the TD 200C, you are not required to use square buttons. However, you must ensure that your button design covers the area of the button as defined in the button template.

After you have used your graphics application to modify the panel image for the faceplate, save the design as a bitmap file (*.bmp).

Figure 3-14 Creating the Panel Image: Import Panel Image

Importing a Panel Image When you have completed the graphical design of panel image for the faceplate, you import the panel image back into the Keypad Designer.

After you open your keypad project (*.td1, *.td2, or *.td4), use the File > Import >Panel Image from File menu command to select the bitmap file that you created with your graphics application.

Figure 3-15 Keypad with a Panel Image

Using the Keypad Designer to Create a Custom Faceplate for your Text Display (TD) Device 3.8 Saving the Keypad to a TD Configuration File


Tip When you design your faceplate, you can create the bitmap with any resolution. However, the size of the background image for the TD device must exactly match the following dimensions:

For the TD 200C: Width: 137 mm (+/- 0.15 mm) (5.42 inches) Height: 65.7 mm (+/- 0.15 mm) (2.58 inches)

For the TD 100C: Width: 79 mm ((+/- 0.1 mm) (3.11 inches) Height: 65.8 mm (+/- 0.1 mm) (2.59 inches)

For the TD400C: Width: 91.5 (+/- 0.1 mm) (3.6 inches) Height: 163.5 (+/- 0.1mm) (6.44 inches)

If your faceplate design does not match these dimensions, the Keypad Designer alerts you before importing the panel image. If you import a panel image with incorrect dimensions, the Keypad Designer resizes your panel image, which could distort the appearance of your faceplate design.

3.8 Saving the Keypad to a TD Configuration File

Saving the Keypad to a TD Configuration File When you save the keypad, you create a TD configuration file (*.td1 for the TD 100C, *.td2 for the TD 200C, and *.td4 for the TD400C). This file contains the following information about the buttons on the keypad:

Number of buttons

Location and sizes of the buttons

Names of the buttons

Functions assigned to the buttons

Panel image (if one was imported)

Use the File > Save or File > Save As menu command to save the configuration of the keypad.

The Text Display Wizard uses this information for configuring the TD 100C, TD 200C, or TD400C. See Chapter 4 for more information.

Using the Keypad Designer to Create a Custom Faceplate for your Text Display (TD) Device 3.9 Reversing the Panel Image


Figure 3-16 Saving the TD Configuration File

Tip The Keypad Designer allows you to save invalid or incomplete configurations. This allows you to save interim versions of your work. However, always ensure that the final configuration of the keypad is valid and complete before using the configuration file (*.tdx) with the Text Display wizard.

3.9 Reversing the Panel Image

Reversing the Panel Image The Reverse Panel Image option only affects the way that the panel image is saved to a file using the File > Export > Panel Image to File menu command. The exported bitmap file can then be inserted into the Microsoft Word template. For more information see the next section, Printing the Panel Image on a Faceplate. The Reverse Panel Image option does not change the layout of the keypad.

Printing a reversed image allows you to orient the side of the faceplate with the ink from the printing process towards the TD device. The operator then touches only the plastic membrane and not the ink when pressing a button. See the figure below..

Printing a non-reversed panel image allows the elements to be read correctly when printed. Use the non-reversed panel image when you print a paper copy of the faceplate for review. See figure below.

Use the File > Export > Reverse Panel Image menu command to select this function. A check mark notifies you that Reverse Panel Image function is selected.

Figure 3-17 Reversed Panel Image

Figure 3-18 Non-reversed Panel Image

3.10 Printing the Panel Image on a Faceplate

Printing the Panel Image on a Faceplate To print your custom-designed panel image onto the blank faceplate material, you must use a laser printer that supports printing transparency material in both the A4 and envelope formats and also supports color printing.

You can print a single panel image directly from the Keypad Designer on the envelope-sized blank faceplate (shipped with the TD 100C and TD 200C device). When you print a single faceplate (File > Print), the panel image is always reversed.

To print multiple panel images, you can use the Microsoft Word template that ensures your panel image design is properly sized. You can print multiple panel images onto the perforated A4-size blank faceplate sheets. See Appendix A for order numbers.

Tip The faceplate material is specially treated on one side to accommodate printing with a laser printer. The treated surface is up (or toward you) when you are holding the material with the cut corner in the top right of the sheet.

Ensure that the material is correctly inserted into the laser printer so that the panel image is printed onto the treated surface of the material. You must print a reversed-panel image version onto the faceplate material. To reverse the panel image, see the previous section, Reversing the Panel Image.

Before printing your panel image onto the blank faceplate sheet, first test your design by printing the panel image onto regular paper. You can then temporarily use the paper faceplate to test the functionality of the design with your TD device.

Using the blank faceplate sheets also allows you to create large quantities of high-quality faceplates by utilizing the professional printing services of shops that specialize in laser printing.



You can order additional blank faceplates in perforated A4-size sheets (10 sheets/package) for the TD 100C, TD 200C and TD400C. The faceplate material is especially designed for printing with laser printers.

The blank faceplate material for the TD 100C, TD 200C and TD400C is available in the sizes below:

Envelope size for printing a single faceplate (TD100C, TD200C): The Keypad Designer prints registration lines for trimming the faceplate to the correct dimensions. (Use a metal straight edge and a knife or razor blade to ensure accurate and straight cuts.) The TD 100C and TD 200C devices ship with a single blank faceplate. The TD400C does not include a single faceplate.

A4 size (210 mm x 297 mm) for printing multiple copies of the faceplate (TD100C, TD200C, and TD400C): You can use the Microsoft Word template to print the faceplate onto perforated areas of the material. You do not have to cut the faceplates from the material. Order these A4 sheets from your Siemens distributor. See Appendix A for order numbers.

Figure 3-19 Printing the Faceplate

Tip Before attempting to print a custom faceplate, ensure that both the printer and the word-processing application are set to the correct paper size:

Single-copy sheet: Set both the printer and word-processing application to print on Envelope.

Multiple-copy A4 sheet: Set both the printer and the word-processing application to print on A4-size paper.



Your computer and your laser printer may have other settings that cause the printer to scale the faceplate to an incorrect size. Always first print a test copy on paper before printing your faceplate onto the blank material.

Printing a Single Faceplate from the Keypad Designer You can print individual faceplates directly from the Keypad Designer:

1. Ensure that the laser printer is set to print envelopes.

2. Insert the envelope-size faceplate material into the tray.

3. Select the File > Print menu command.

4. Select the laser printer and click OK.

5. Using the cut lines and a paper cutter, cut the faceplate from the material

Figure 3-20 Printing a Single Faceplate

Tip For best results use a razor-blade cutting knife with a metal straight edge to cut the faceplate from the material. You can also use a high-quality paper cutter. Be especially careful when using scissors or similar tools. Scissors are more likely to stretch or tear the material, causing irregular edges for the faceplate.

Printing the Faceplate from a Word-Processing Application You use a word-processing application (such as Microsoft Word) to print multiple copies of the faceplate onto A4-size blank faceplate material. After you export the panel image of the faceplate into a document, you adjust the location of the panel images and print the document.

Tip Siemens provides document files (in 6 languages) for Microsoft Word that helps you to align the panel images for the perforations on the A4 blank faceplate material. To open these documents, browse to the Templates subdirectory under the Keypad Designer application (C:/Program Files/Siemens/TD Keypad Designer/Templates) and select the template for your TD device and language.

Before printing the faceplate onto the blank faceplate material, you must ensure that the document and the printer settings are both set to print on A4 paper. Also, ensure that the laser printer itself is configured to print A4 paper.

After you print the faceplate document, you use the perforations to remove the faceplates from the sheet.



Figure 3-21 Printing Multiple Faceplates

To export the panel image to your word-processing application:

1. Open your word-processing application (Microsoft Word) and open the template file.

2. Open the Keypad Designer

3. In the Keypad Designer, select the File > Export > Panel Image to File menu command to create a bitmap file that you insert into the word-processing application.

4. Insert the panel image into the document by using the word-processing application to insert the bitmap file (*.bmp) that you created with the Keypad Designer.

5. Follow the instructions in the template file for positioning and sizing the faceplate.

6. After inserting the panel image into the document, save the document using the File > Save As menu command of the word-processing application.

With the panel images saved in your document, you can print the document to your laser printer.

Tip Before printing the panel image onto the blank faceplate material, first test your design by printing the faceplate onto regular A4 paper.

Using the Keypad Designer to Create a Custom Faceplate for your Text Display (TD) Device 3.11 Installing the Printed Faceplate onto the TD device


3.11 Installing the Printed Faceplate onto the TD device

Installing the Printed Faceplate onto the TD 100C, TD 200C, and TD400C Use the following procedure to install your custom faceplate on the TD device. The example shown here is for the TD 200C. Installing a faceplate on a TD 100C and TD400C is similar; the differences are noted below. To prepare for installation, remove the protective film covering the display window of the TD device and the back of the preprinted (standard) faceplate. The protective film is blue for the TD 100C and the TD 200C, and transparent for the TD400C.

1. If your TD device has a strip of protective paper, remove the strip to expose a strip of the adhesive. For the TD 200C and TD400C, it is on the left side; for the TD 100C, it is on the right side of the device.

2. Carefully align your custom faceplate on the entire TD device, and then seal the faceplate to the exposed adhesive by pressing down on the left (TD 200C and TD400C) or on the right (TD 100C) side of the faceplate.

3. Carefully lift back the unadhered faceplate and remove the rest of the protective paper from the TD device.

4. Carefully position the faceplate onto the TD device. Firmly press the faceplate onto the adhesive, taking care to remove any air bubbles that may have been trapped underneath.

NOTICE

Do not use excessive force or a hard (or sharp) tool when you install the faceplate onto the TD400C device.

If you use excessive force a hard tool when you press the faceplate onto the TD400C device, it may cause damage to the springs under the faceplate.

Ensure that excessive force or a hard (or sharp) tool is not used when you install the faceplate onto the device

Refer to Chapter 2 for additional information about installing the TD devices, including the dimensions for the faceplate.

Overview of Chapter 4 You do not configure or program the TD device. The Text Display wizard creates a parameter block that stores the configuration, screens and alarms for the TD device. The S7-200 CPU stores the parameter block in V memory. At power-up, the TD device reads the parameter block from the S7-200 CPU.

You use the Text Display wizard of STEP 7-Micro/WIN to perform the following tasks:

Configuring the parameters for the TD device

Creating the screens and alarms to be displayed on the TD device

Creating the language sets for the TD device (TD 200, TD 200C and TD400C only)

Assigning the V memory address for the parameter block

Tip To connect your TD device to a network, you use the Diagnostic or TD Setup Menu of the TD device to set up the network addresses, baud rate and other parameters. Refer to Chapter 5.

4.2 Overview of the Configuration Tasks

Overview of the Configuration Tasks The S7-200 CPU stores the configuration data for the TD device, including the screens and alarms, into a parameter block (located in V memory). The Text Display wizard creates the parameter block. When you download your project (user program and data block) to the S7-200 CPU, you also download the parameter block as part of the data block.

You do not configure or program the TD device. At power-up, the TD device reads the parameter block from the S7-200 CPU.

As shown in the figure below, you use the Text Display wizard of STEP 7-Micro/WIN to create the parameter block for the TD devices. The next figure shows the sequence of the tasks required for configuring the parameters of the TD device.

Figure 4-8 Enabling the CPU Functions for the TD 100C



Selecting the Update Rate for the TD Device You can select how often the TD device performs a read operation to update the information from the S7-200 CPU. You can select from "As fast as possible" to "Every 15 seconds" (in one-second increments).

Selecting the Language and the Character Set The Text Display wizard allows you to select the language for the system menus and prompts of the TD device. This selection does not affect the language setting for the screens or alarms that you enter. You select a character set that supports the language of the text that you enter for the screens and alarms. (If the character set does not match the Windows character set, the Text Display wizard may not display the characters correctly. The TD device displays these characters correctly.)

Select the language for the system menus and prompts displayed by the TD device.

The TD devices support English, French, German, Italian, Simplified Chinese, and Spanish.

Select the character set for the text in your alarms and screens.

Refer to Appendix A for descriptions of the character sets supported by your TD device. The Simplified Chinese Character Set is an electronic file that resides on the STEP 7-Micro/WIN documentation CD

These settings define a language set for the TD device. The Text Display wizard also provides a series of dialogs for copying the alarms and screens to create additional language sets (TD 200, TD 200C, and TD400C). For each language set, you select the language and the character set.

Figure 4-9 Localizing the TD Device



Tip When you create multiple language sets (TD 200, TD 200C, and TD400C), the Text Display wizard copies the alarms and screens from the primary language set to the other language set. You then edit the screens and alarms to translate the text displayed for the new language set.

If you need to modify the screens or messages (such as to add a new variable or to add a new alarm), you must edit the primary language. The Text Display wizard copies these changes to the other language sets.

The Text Display wizard only allows you to change the text in the other language sets.

Selecting the Font Size (TD 100C, TD400C) The TD 100C and TD400C support two font sizes for displaying user and alarm messages. Larger fonts are easier to read, but will result in fewer characters per user message. You select the font size for the TD100C as shown in the figure below. You select the font size for the TD400C when you configure the alarm or user message (refer to the section on configuring screens and alarms in this chapter).

The following font sizes are available:

TD 100C: Small font (16 ASCII or 8 Chinese characters per line)

Large font (12 ASCII characters per line)

Font selection applies to all messages and screens

TD400C:

Small font (24 ASCII or 12 Chinese characters per line) Large font (16 ASCII or 8 Chinese characters per line)

Each alarm or screen can have a different font

Figure 4-10 Selecting the Font Size (TD 100C)



Loading a Custom Keypad (TD 100C, TD 200C, and TD400C Only) The TD 100C, TD 200C, and TD400C allow you to create a custom keypad. As described in Chapter 3, you can insert buttons onto the keypad. The Keypad Designer saves this configuration to a file (*.td1 for the TD 100C, *.td2 for the TD 200C, and *.td4 for the TD400C).

To load the keypad configuration file into the Text Display wizard:

Select the option, Use a custom keypad created with the Keypad Designer. (Find this check box in the Options area of the Configure Keypad Buttons dialog. See Figure below.)

Browse to the keypad configuration file (*.tdx) that you created with the Keypad Designer.

The Text Display wizard loads the keypad configuration file and updates the table of buttons and the button symbols.

The Text Display wizard lists only those buttons that you had defined with the Set Bit functionality when you created the buttons with the Keypad Designer.

Figure 4-11 Configuring the Functions for the Buttons (TD 200C)



Figure 4-12 Configuring the Functions for the Buttons (TD400C)

Configuring the Buttons on the Keypad As shown in previous figure, the Configure Keypad Buttons dialog allows you to select a symbol name and an action for each of the configurable buttons on the TD device.

The TD 200 keypad provides 4 configurable buttons and a SHIFT button that can be configured for up to 8 bits in the S7-200 CPU

The TD 200C can be configured for up to 20 configurable buttons

The TD 100C can be configured for up to 14 configurable buttons

The TD400C can be configured for up to 15 configurable buttons

Tip The Configure Keypad Buttons dialog of the Text Display wizard displays only those buttons that set bits in the S7-200 CPU. The Text Display wizard does not list the buttons with other functionality, such as ESC or SHIFT.

The symbols that you assign to the buttons on the keypad allow the logic of your user program in the S7-200 CPU to interact with the TD device. (The Text Display wizard suggests a symbol for these buttons. You can accept the recommendation or enter a new symbol for the button.)

For each button, you configure the type of action:

Set bit: When you press the button on the TD device, the TD device sets the bit on in the S7-200 CPU. The bit stays on until the logic of your user program in the S7-200 CPU resets the bit.

Momentary contact: When you press the button on the TD device, the TD device sets the bit on in the S7-200 CPU. When the TD device button is released, the TD device turns the bit off in the S7-200 CPU.

Using the Text Display Wizard to Configure the S7-200 CPU for Your Text Display (TD) Device 4.4 Configuring the Screens for the Text Display Device


Tip The TD device only sets the bit on or off in the S7-200 CPU a single time when the TD device button is either pressed or released.

Tip The TD device can display a special icon that provides visual feedback to the operator and shows that the set bit key was pressed in the CPU. To enable this feature, check the box at the bottom of the Configure Keypad Buttons wizard screen (see the previous figure).

4.4 Configuring the Screens for the Text Display Device

Configuring the Screens for the TD Device The TD device supports a set of user-defined screens and a user menu. Screens allow the operator using the TD device to initiate the interaction with the S7-200 CPU. See the figure below.

User menu: Provides a hierarchy for switching between groups of screens. For the TD 200, TD 200C, and the TD400C you configure up to 8 entries in the user menu. For the TD 100C, you configure up to 4 entries in the user menu.

Screens: You create up to 8 screens for each entry in the user menu.

The TD device displays the screens and the items on the user menu in the order that you configure them.

If you configure both alarms and screens, you also designate the default display mode for the TD device.

The operator uses the buttons on the keypad to navigate through the user menu or the screens that you configured.

Figure 4-13 Configuring the Screens

The buttons that a TD operator could use to navigate from a user menu to the screens associated with that item in the menu are shown below.



Figure 4-14 Navigating through a Hierarchy of User-Defined Screens

Tip The screens in the TD 200 and TD 200C are always two lines. The screens in the TD 100C are always four lines. The screens in the TD400C can be 4 lines (with the small font), or 2 lines (with the large font).

After you have configured the TD device, you can configure the screens and the user menu. Click the user menu icon to start creating the user menu for the screens. See the figure below.

For the user menu, you perform the following tasks:

Create the groups (names) to be displayed on the user menu

Determine the sequence of the groups listed on the user menu

For the screens, you perform the following tasks:

Add the screens to each group (on the user menu)

Create the text message (and add variables) for each screen



Add icons to the text message (TD 200C and TD400C only)

Determine the sequence of the screens for each group

Figure 4-15 Selecting the Screen Configuration Tasks

Creating the User Menu The process for creating the screens and user menu is not sequential: You can choose to enter the screens for each individual group before creating the next group, or you can enter all of the groups for the user menu before creating any of the screens.

To configure the user menu, you enter the names for each group of screens. See the figure below for an example of the TD400C. The Text Display wizard displays a green ENTER icon (and blue arrow) to show which group is selected.

To create the screens associated with a group on the user menu:

1. Move the cursor to the box that designates the group on the user menu.

2. Click the Add Screen button.

3. Create the text for the screen.

4. Click the Add Screen button to create the other screens in this group.

Use the Move Choice Up and Move Choice Down buttons to change the sequence of the groups listed on the user menu.



Figure 4-16 Defining the User Menu

Creating the Text for a Screen Your screen message can contain the following elements:

Text: Enter your text in the green area that represents the text display area of the TD device

Icons (optional): Click the icons in the toolbar to insert the icon into the text message (TD 200C and TD400C only)

Variable data (optional): Click the Insert PLC Data button to embed a variable into the text message

Font selection (TD400C only): Select the Font button to select a font. You can select a different font for each row of the user message.

You can designate the screen to be the default screen. The TD will show the default screen after being powered on.



Figure 4-17 Creating the Message for a TD 200C Screen

Figure 4-18 Creating the Message for a TD400C Screen

Embedding a Variable into the Text of a Screen You can embed a variable data field into the text of the screen. To open the Insert PLC Data dialog, move the cursor to the location for the variable in your text and click the Insert PLC Data button. As shown in the figure below, you enter the following information:



Tip For the TD 200, TD 200C, and the TD400C, you can embed up to 6 variables per screen. For the TD 100C, you can embed up to 1 variable per line (4 variables per screen).

Data address:

– VB: Numeric String, Text String

– VW: Signed, Unsigned

– VD: Real, Signed, Unsigned

Data Format: Signed, Unsigned, Real, Numeric String, or Text String

Digits to the right of the decimal: Up to 7

Figure 4-19 Inserting PLC Data

The TD device rounds a real number to the specified decimal place. For example, if the real number value is 123.456 and you select 2 digits to the right of the decimal, the TD 200 displays this value as: 123.46.

Tip Refer to the SIMATIC S7-200 Programmable Controller System Manual for information about the data types or for the memory addresses supported by the S7-200 CPU.

You can also allow the operator to modify the data stored at this memory location in the S7-200 CPU.

You can require the operator enter the TD password before editing the variable. (You must have enabled password-protection for the TD device.)

You can configure the cursor to jump to the variable field.

You can define a symbolic name for the variable. You use the symbolic name to access this data with your user program.

Clicking OK inserts the variable into the text of the screen. The Text Display wizard inserts a block of 4 characters to show the presence of the variable. The value to be displayed for the variable is right-justified at that location (anchored to the right-most character).

Data values are always right-justified to the right-most character of an embedded variable. As a data value grows in magnitude, it utilizes more spaces to the left of the anchor point and can overwrite the text characters. Always provide sufficient space between the end of your text and the anchor point to allow for the expected range of the data value.



Tip The actual number of characters used to display a value varies with the size of the value. To help calculate the number of characters required for displaying the value of the variable, see the examples listed in Table 4-1.

The TD device displays all values as decimal numbers. Positive signed values are displayed without a sign, and negative signed values are displayed with a leading minus sign. Unsigned values are displayed without a sign. A leading zero is used for all fractional numbers (for example, 0.5). Real numbers are displayed with the number of decimal places you specify. The value is rounded to the specified decimal place.

1 The length of a line (number of characters in a line) varies by TD model and character size. The line length is always 20 for a TD 200 or TD 200C. The line length is either 12 or 16 characters for a TD 100C. The line length for the TD400C depends on the font you selected. If you selected a small font, you have 24 ASCII characters or 12 Chinese characters per line. If you selected a large font, you have 16 ASCII characters or 8 Chinese characters per line.

Embedded String Variables There are special considerations when you set up a string variable for the TD devices. String variables are positioned the same as numeric variables, that is, the right-most character of the variable is positioned at the right-most position of the embedded variable in the Text Display wizard. This can cause problems when you want to place a text string adjacent to other text in the message.



When you embed a string variable in a TD alarm or screen, the Text Display wizard shows the embedded variable occupying 4 character spaces (or 2 Chinese characters) for the variable. These 4 spaces are the right-most 4 characters of the text string. If you want to have the text adjacent to other text, that is, to the left of the variable, the characters in the string need to be left-justified and padded with spaces to place the text in the proper position on the display.

For example: Assume that we want to show the pump status and that status is either "Pump OK" or "Pump High Temp". The screen display shows the word "Pump" followed by a string variable which is set to either "OK" or "High Temp". You set up the display in the Text Display wizard like this:

Pump _ _ _ _ _ _

The underlines are blank spaces, and the squares are the embedded variable (which takes up 4 character spaces). You can create 2 strings that you copy into the variable based on the current pump status. These strings are "OK" and "High Temp". These strings are displayed in the figure below.

Figure 4-20 Embedded String Variable

The right-most character of the "OK" string is placed in the right-most position of the embedded variable. Since the string is only 2 characters, it displays on the right side of the display where the embedded variable is placed.

To make the "OK" string display next to "Pump", simply add blank spaces to the "OK" string to match the length of the other string. The "OK" string would become "OK ". Now the string is displayed in the figure below.

Figure 4-21 Embedded String Variable with Blank Spaces

The figure below shows how to create the two strings using the STR_CPY command. Note how the "OK" string is padded with blank spaces to left justify the characters on the TD display.

Figure 4-22 Using STR_CPY to Create Strings

4.5 Configuring the Alarms

Configuring the Alarms Alarms allow the user program in the S7-200 CPU to initiate interaction with the operator by displaying an alarm message on the TD device. When your user program sets an alarm bit, the TD device reads the text of the alarm from the S7-200 CPU.

The figure below lists the key tasks for creating alarms. You configure the following information for each alarm:

Number of alarms: Up to 80 alarms for the TD 200, TD 200C and TD400C, and up to 40 alarms for the TD 100C to be configured for the TD device

Text message for the individual alarms



Priority for the alarms is determined by the sequence in which you configure the alarms:

– The first alarm has the highest priority

– The last alarm has the lowest priority

Acknowledgement (if required)

Figure 4-23 Configuring the Alarms

The TD 200, TD 200C, and TD400C devices store up to 80 alarms, and the TD 100C device stores up to 40 alarms. The TD displays the alarm messages according to priority.

The operator uses the buttons on the keypad to scroll through the list of alarms. See the figure below.

Figure 4-24 Alarm Messages



Determining the Type of Operator Interaction for an Alarm The Text Display wizard allows you to determine the type interaction required by the operator for an alarm. If the user screens are set as the default display mode for the TD device and an alarm is enabled, an alarm indicator will begin to flash on the TD display. The indicator is large if there is an alarm enabled that requires acknowledgement. The indicator will be small if the alarms do not require acknowledgement. The user can switch to the alarm display to view the alarms.

The alarm display will show one or more alarms in priority order. An UP or DOWN arrow in the right-most character position indicates more alarms are active, but not visible on the display. The operator can press either the UP or the DOWN arrow key to scroll through the other enabled alarms.

The operator can edit or accept variable values by pressing the ENTER key. The TD device will write the updated variable value to the CPU and set the edit notification bit for that variable when the operator presses the ENTER key. The TD device then moves the cursor to the next editable variable. Pressing ENTER for the last editable variable of an alarm writes this last value to the S7-200 CPU and the TD device then resets the alarm enable bit. For more information on editing variables, see Editing a Variable that is Embedded in an Alarm or a Screen in Chapter 5.

Every alarm falls into one of four possible alarm acknowledgement and editing types. This section explains specifically how each alarm type is handled by the TD device. The four alarm types follow:

No acknowledgement required, no edits allowed

Acknowledgement required, no edits allowed

No acknowledgement required, edits allowed

Acknowledgement required, edits allowed

No Acknowledgement Required, No Edits Allowed In this combination of no acknowledgement required and no edits allowed, the TD device simply displays the alarm. The ENTER key has no function since there are no editable variables within the alarm. The alarm may contain variables that are updated at the update rate of the TD device. This type of alarm is replaced on the display if a higher priority alarm is enabled by the S7-200 CPU. The operator can either press the UP or the DOWN arrow key to scroll to other alarms or press ESC to return to the menus.

The TD device does not clear the corresponding alarm-enable bit in the S7-200 CPU.

Acknowledgement Required, No Edits Allowed In this combination of acknowledgement required and no edits allowed, the TD device displays the alarm and makes the entire alarm flash (blink) until the operator presses ENTER to acknowledge the alarm. Variable values are updated from the S7-200 CPU at the normal update rate while the alarm is flashing.

When the operator presses ENTER, the TD device:

Sets the acknowledgement-notification bit for this alarm.

Clears the alarm-enable bit for this alarm. This causes the alarm to be removed from the display on the next update cycle.



Another alarm cannot replace the one flashing until the operator acknowledges the flashing alarm. This is also true even if a higher priority alarm is enabled in the S7-200 CPU. If the TD device is configured for single line alarms and the CPU enables a higher priority alarm, the flashing alarm shifts down to the next line of the display. The operator cannot press the UP or the DOWN key to scroll through other enabled alarms until the current alarm is acknowledged.

No Acknowledgement Required, Edits Allowed In this combination of no acknowledgement required and edits allowed, the TD device displays a alarm and then waits for the operator to edit a value in the alarm. All of the variables within the alarm are updated at the update rate. Since the alarm does not require acknowledgement, this type of alarm is removed from the TD device display if a higher priority alarm is enabled in the S7-200 CPU.

Acknowledgement Required, Edits Allowed In this combination of acknowledgement required and edits allowed, the TD device displays the alarm, causes the entire alarm to flash (blink), and then waits until the operator acknowledges the alarm and edits or accepts the values in the alarm. This type of alarm requires that the operator edits or accepts the values displayed in the alarm. If the operator aborts the edit by pressing the ESC key before editing all the values in the alarm, the alarm flashes to indicate that edits are still required.

When the alarm is enabled in the S7-200 CPU, the TD device notes this and, if there is space available on the display, reads the alarm from the CPU. The TD device then displays the alarm and causes the entire alarm to flash to notify the operator that the alarm is present and must be acknowledged.

Setting the Default Display Mode and Alarm Parameters The TD device supports alarms that are displayed under program control. After you have configured the TD device, you can configure the alarms. When you configure the alarms, you also select either screens (default) or alarms as the default display mode for the TD device.

Click the Alarms icon to start creating alarms. As shown in the figure below, you select the following information:

Default display mode: Select either alarms or screens as the default display mode. This selects which type of messages the TD device displays after powering up or after a prolonged period of no key presses by the user.

Size of the alarms: Select 1 line or 2 lines (TD 100C, TD200 and TD400C), or 4 lines (TD400C only).

For Chinese characters, select either one row or two rows of text.



Figure 4-25 Configuring the TD 200C Alarm Options

Figure 4-26 Configuring the TD400C Alarm Options

Tip The TD 200, TD 200C, and the TD400C support up to 80 alarms, and the TD 100C supports up to 40 alarms. The priority for the alarms is determined sequentially, from the first alarm (highest priority) to the last (lowest priority).

Entering the Text for an Alarm Clicking Next displays the Alarms dialog shown in the figure below. You can select a symbolic name for the alarm. The user program uses the symbolic name to enable (and display) the alarm. Click the New Alarm button to create the alarm message. Your alarm message can contain the following elements:

Text: Enter your text in the green area that represents the text display area of the TD device

Icons (optional, TD 200C and TD400C): Click the icons in the toolbar to insert the icon into the text message



Variable data (optional): Click the Insert PLC Data button to embed a variable into the text message

Fonts: For the TD400C you select the font to use for the alarm message

To ensure that important alarms are acknowledged by an operator, you can configure the alarm to require acknowledgement.

You select the symbolic name for the acknowledgement bit for the alarm. The user program uses this symbolic name to report that the alarm has been acknowledged.

To acknowledge an alarm with the TD device, the operator selects the alarm and presses ENTER.

Figure 4-27 Creating the Text for an Alarm



Embedding a Variable into the Text of an Alarm You can embed a variable data field into the text of the alarm. To embed a variable, move the cursor to the location for the variable in your text and click the Insert PLC Data button. As shown in the figure below you enter the following information:

Tip For the TD 200, TD 200C, and the TD400C, you can embed up to 6 variables per alarm. For the TD 100C, you can embed up to 1 variable per line (1 for one-line alarms, and 2 for two-line alarms).

Data address:

– VB: Numeric String, Text String

– VW: Signed, Unsigned

– VD: Real, Signed, Unsigned

Data Format: Signed, Unsigned, Real, Numeric String, or Text String

Digits to the right of the decimal: Up to 7

– The TD device rounds a real number to the specified decimal place. For example, if the real number value is 123.456 and you select 2 digits to the right of the decimal, the TD 200 displays this value as: 123.46.

4.6 Configuring the Language Sets (TD 200, TD 200C, and TD400C)

Configuring the Language Sets for the TD Device (TD 200, TD 200C, TD400C) The Text Display wizard allows you to configure multiple language sets for your TD device, including not only the system prompts or messages, but also for the user alarms, user menus, and screens. The Text Display wizard copies the user alarms and user screens that you have configured into the language set. You must manually enter the translated text for each alarm, menu, or screen.

For each language set, you select the following information:

Language for the system prompts

Character set

Identifier

You also select which of the language sets is the primary language for the TD device.

Figure 4-29 Configuring the Languages for the TD Device

Tip When you create multiple language sets, the Text Display wizard copies the user alarms, menus, and screens from the primary language set to the other language set. You then edit the alarms, menus, and screens to translate the text displayed for the new language set.

If you need to modify the screens or messages (such as to add a new variable or to add a new alarm), you must edit the primary language. The Text Display wizard copies these changes to the other language sets.

The Text Display wizard only allows you to change the text in the other language sets.

After you have configured the alarms and screens for one language set, you can add a new language set:

1. Click the icon to start configuring the language sets for the TD device.

2. Add a new language by selecting New Language Set.

3. Select an existing language set to be the source for the new language set.



4. (Optional) Select the option for primary language to configure the new language as the default language set for the TD device.

5. Click the Next button to display the Localize Display dialog.

Figure 4-30 Adding a Language

The Localize dialog configures the menus and character set for the TD device

1. Select the language for the system menus and prompts of the TD device.

2. Select the character set for the text.

3. Enter the name to be displayed on the TD device for this language set.

After you click the Next button, the Text Display wizard copies all of the user alarms, menus, and screens from the selected language set to the new language set.



Figure 4-31 Localizing the Display

Notes for Using the Simplified Chinese Character Set Tip The Simplified Chinese character set requires a Chinese version of Windows or a Chinese emulator to properly display Chinese characters in the Text Display wizard. You must start the Chinese emulator before you start the STEP 7-Micro/WIN software.

On the TD 200C, and the TD 200, you can display up to 20 single-byte characters per line of your message. Because Simplified Chinese uses double-byte characters, you can display up to 10 double-byte characters per line for a message in Chinese.

On the TD 100C, you can display up to 16 single-byte characters per line of your message. Because Simplified Chinese uses double-byte characters, you can display up to 8 double-byte characters per line for a message in Chinese.

On the TD400C using a small font, you can display up to 24 single-byte characters per line of your message. Because Simplified Chinese uses double-byte characters, you can display up to 12 double-byte characters per line for a message in Chinese. If you selected a large font, you can display up to 16 single-byte characters or 12 Chinese characters per line.

The standard ASCII characters, such as numbers, punctuation, and upper and lowercase alphabet characters, are available when using the Simplified Chinese character set. Depending on your keyboard and/ or emulator, some of these standard characters may be formatted as single-byte characters instead of the double-byte characters like the Simplified Chinese characters. Standard ASCII characters and Chinese characters can be mixed on the TD display.

The Text Display wizard displays 8, 10 or 12 double-byte character places for the text of a screen or alarm. You can fit any of the following combinations into a character position:

1 double-byte character

2 single-byte characters (standard ASCII)

1 single-byte character and 1 single-byte blank

Using the Text Display Wizard to Configure the S7-200 CPU for Your Text Display (TD) Device 4.7 Assigning the V Memory Address for the Parameter Block


You cannot fit one single-byte character plus one double-byte character in a character position.

The TD 100C does not support the entire Simplified Chinese character set, but does support the most commonly used characters. Characters that are not supported by the TD 100C are displayed as a square.

See the Simplified Chinese Characters Set on the STEP 7-Micro/WIN documentation CD for a list of characters supported by the TD 100C.

4.7 Assigning the V Memory Address for the Parameter Block

Assigning the V Memory Address for the Parameter Block The Text Display wizard creates the parameter block that you download to the S7-200 CPU with your user program. The parameter block includes the configuration data for the TD device and any screens and alarms that you created.

The Text Display wizard calculates the amount of memory required for the parameter block and suggests a starting address in V memory.

The default location for the parameter block is VB0.

Figure 4-32 Assigning the Address of the Parameter Block

4.8 Finishing the Configuration for the TD Device

Finishing the Configuration for the TD Device After you complete the configuration for your TD device, the Text Display wizard displays a summary dialog. (See the figure below.)

If you enter a name for the TD configuration, STEP 7-Micro/WIN creates an entry in the project tree for the TD configuration.

STEP 7-Micro/WIN also creates the following subroutines:

TD_CTRL_x (where x is the TD configuration number)

– This subroutine ensures that all updates for the TD device (such as alarms or changing the language setting) occur immediately.

– Your user program should use SM0.0 to call this subroutine every scan

Using the Text Display Wizard to Configure the S7-200 CPU for Your Text Display (TD) Device 4.8 Finishing the Configuration for the TD Device


TD_ALM_x (where x is the TD configuration number)

– Your user program uses this subroutine to call the alarm by the symbolic name (configured by the Text Display wizard). This subroutine requires the S7-200 Symbol Table.

– Your user program should call TD_ALM_x on every scan when the alarm is present.

Figure 4-33 Summary Dialog

Note

The TD_CTRL_X subroutine will clear the alarm enable bits each time it is called. This behavior could be problematic if the TD configuration contains alarms that require acknowledgement. The TD_CTRL_x subroutine may disable these alarms before they can be displayed and acknowledged on the TD device. Your program logic must ensure that any TD_ALM_x alarm subroutine that requires acknowledgement remains enabled until the TD device writes the alarm acknowledgement bit in the CPU.

Operating Your Text Display (TD) Device 55.1 Overview

Operating Your TD Device Included in this chapter is information about routine operator tasks, such as entering and releasing the password, editing variables embedded in a message or screen, and checking the status information of the S7-200 CPU. This chapter also describes the less-routine diagnostic functions provided by the TD device for troubleshooting problems in the S7-200 CPU, such as forcing I/O or changing the operating mode

5.2 Using the Text Display Device to Access Screens and Alarms

Using the TD Device to Access Screens and Alarms The TD devices allow you to structure information as either screens or bit-enabled alarm messages. You use the buttons of the keypad of the TD device to navigate through the screens and menus:

TD 200: Uses the standard TD keypad.

TD 100C, TD 200C, and TD400C: Allow you to change the configuration and use your own custom-designed keypad. (If there is no custom configuration, the TD 100C,TD 200C and TD400C defaults to the standard TD keypad configuration.)

Tip For more information about configuring the functionality of the buttons on the keypad:

Chapter 4 provides information about configuring the buttons for the TD devices. The TD configuration is downloaded to the S7-200 CPU with your user program.

Chapter 3 provides information about creating a custom keypad layout for the TD device, and assigning specific functionality for each button. (You then integrate the custom keypad with the screens and alarm messages as described in Chapter 4.)

Operating Your Text Display (TD) Device 5.2 Using the Text Display Device to Access Screens and Alarms


As shown in Figure 5-1 and Figure 5-2, the standard TD keypad provides the following buttons:

ENTER and Escape (ESC) buttons:

– ENTER selects a menu item or confirms a value.

– ESC exits from a menu or cancels a selection.

Configurable buttons:

– Function keys perform the task that you configured with the Text Display wizard. The TD 200, TD 200C, and TD400C uses F1 to F4, and the TD 100C uses F1 and F2.

– SHIFT on the TD 200, TD 200C and TD400C allows the function keys (F5 to F8) to perform the task that you configured with the Text Display wizard.

Arrow buttons:

– UP arrow scrolls (upwards) through menu items or increments a value that can be edited.

– DOWN arrow scrolls (downwards) through menu items or decrements a value that can be edited.

– LEFT and RIGHT arrows move the cursor left or right within the message (TD 100C, TD 200C, and TD400C only). For a TD 200, use SHIFT+DOWN to move right and SHIFT+UP to move left. You can also use ENTER to move to the next variable message.

To select a menu item, use the UP and DOWN arrows to scroll through the list of available items. The TD device highlights the menu item.

Pressing ENTER selects the highlighted item.

Pressing ESC returns to the previous menu or screen.

Display Backlight on the TD400C The TD400C allows you to set the amount of time that the display backlight is on. This allows you to extend the life of theTD400C by turning off the backlight when the display is not needed.

You can configure the TD400C display backlight on time:

From 1 to 59 minutes in 1 minute increments

Always on

1, 2, 4, or 8 hours

Default on time (10 minutes)

The backlight will turn on when:

The TD400C is powered on

The S7-200 CPU forces a reset of the TD400C with the TD_Reset bit in the TD parameter block.

You press a key. The time is extended each time a key is pressed.

A new alarm is read from the S7-200 CPU

When the display backlight is turned on, the backlight is on for the time that you configured in the TD Setup menu.

If the backlight is currently off and you press a key, the first keypress will turn on the backlight, but will not execute the key function. You must press the key a second time to execute the key function. There will be no audio or visual feedback for the first keypress that turns on the backlight. This lets you know that the key did not execute the key function and you must press the key again.

If your TD400C has an alarm that requires acknowledgement (an alarm that flashes or blinks), and that alarm is enabled, the display backlight will be on until you acknowledge the alarm.



Displaying Information on the TD Device The TD device provides both screens (user-defined menus with associated screens of information) and bit-enabled alarm messages:

Menu: A menu is a list of items that select a grouping of related screens. The TD 200, TD 200C and the TD400C have 8 menus available; the TD 100C has 4 menus available

Screen or alarm:

– A screen or alarm for the TD 200 and TD 200C displays up to two lines of text that provide information for the operator. Each line can be up to 20 characters of text and data. A screen contains up to 40 characters of text and data. An alarm can be either 1 or 2 lines.

– A screen or alarm for the TD400C displays up to four lines of text that provide information for the operator. Each line can be up to 24 characters of text and data. A screen contains up to 96 characters of text and data. An alarm can be either 1, 2, or 4 lines.

– A screen or alarm for the TD 100C displays up to four lines of text that provide information for the operator. (Each line can contain either 12 or 16 characters of text and data. A screen contains 48 or 64 characters of text and data. An alarm can be either 1 or 2 lines.)

The textual message of the screen or alarm can convey information for the operator and can also allow the operator to interact with the S7-200 CPU by changing the embedded value of a variable (such as a set point or limit).

You can configure the TD device to display screens (which are initiated by operator action) and bit-enabled alarms (which are generated by the S7-200 CPU). You can also configure the TD 200 and TD 200C, and TD400C device to display an icon to alert the operator of some event or action required. (Refer to Chapter 4 for information about configuring the TD device.)

Tip Pressing ESC returns you to the previous menu. If there is no activity for 20 seconds (no button pressed), the TD device returns to the default display mode.

The operator uses the buttons on the keypad to navigate through the menu or a list of text. Figure 5-2 shows the buttons that an operator could use to navigate from a user menu to the screens associated with that item in the menu. Figure 5-3 shows how to navigate through the alarms. The TD 200, TD 200C, and the TD400C have eight menus available, and the TD 100C has four menus available.

Figure 5-3 Displaying and Acknowledging Alarms

Operating Your Text Display (TD) Device 5.3 Accessing the Menus and Screens


Using the TD Device to Edit Variables in the S7-200 CPU A screen or alarm message can contain an embedded variable field that allows an operator to respond by changing the value of the variable. The operator uses the keypad to edit variables:

Selecting the Screen: The operator uses the UP or DOWN arrows to display the screen that contains the variable to be edited. (From a menu, the operator presses ENTER to access the group of screens.)

Navigating to the variable: The operator presses ENTER to navigate to the first editable variable.

Changing the value of the variable: Pressing the UP arrow increments (increases) the value, and pressing the DOWN arrow decrements (decreases) the value. (Pressing and holding the UP or DOWN arrow accelerates the operation.) Pressing both SHIFT+ENTER resets the variable to 0. Pressing ESC aborts the edit.

Press LEFT or RIGHT to move the cursor position within the variable. The TD 200 uses SHIFT+UP to move left and SHIFT+DOWN to move right.

Updating the data in the S7-200 CPU: Pressing ENTER writes the updated value for the variable to the S7-200 CPU and moves the cursor to the next editable variable on the screen.

For more information about editing variables, see the section Editing a Variable that is Embedded in an Alarm or a Screen in this chapter.

5.3 Accessing the Menus and Screens

Accessing the Menus and Screens When you configured the TD device (as described in Chapter 4), you created the screens and alarms for the TD device. If you configured both alarms and screens, you also designated which type of message (screens or the alarms) would be the default display mode for the TD device. After power-up or after a period of inactivity, the TD device returns to the default display mode.

In addition to the screens and alarms that you configured, the TD device provides standard functions that the operator can access from system-level and pre-defined menus. From the default display mode, the operator uses ESC to access the menu hierarchy. The operator then presses ENTER to select the menu item for accessing the other menus or functions. Figure 5-5 and Figure 5-6 show the hierarchy of menus for these functions for the TD devices. (The menus show all of the functions that are available on the TD device. For some of the functions to be listed on the menu, you must have enabled the function during configuration. See Chapter 4.)

Operating Your Text Display (TD) Device 5.4 Entering and Releasing a Password


5.4 Entering and Releasing a Password

Entering and Releasing a Password You use the Text Display wizard of STEP 7-Micro/WIN to configure the password for the TD device. Refer to Chapter 4 for information about configuring the TD device. To ensure that an unauthorized user does not have access to the TD device during an interval for the automatic time-out, you can use the Release Password feature.

Certain operations (such as forcing I/O or making a memory cartridge) may also require that the operator enter the 8-character CPU password for the S7-200 CPU. (You must have enabled the S7-200 CPU for password-protection in order for the TD device to prompt the operator for the CPU password.)

Entering the Password If configured for a password, the TD device prompts the operator to enter the 4-digit password before allowing the operator to access screens or menus. If the password uses fewer than 4 digits, the operator must press ENTER for the unused (remaining) characters.

Use the UP or DOWN arrow to select each digit of the password, pressing ENTER to move to the next digit. You can also use the RIGHT and LEFT arrows to move within the password.

The TD device provides a time-out feature which automatically restores password protection after a period of inactivity. If no buttons have been pressed after 2 minutes, the TD device then requires a password again before allowing an operator to access menus or to edit variables.

Releasing the Password In order to provide additional security for your application, the TD device provides a Release Password command that immediately restores the password-protection. The TD device then requires that the operator enter the password before allowing access. The Release Password command prohibits another person from using the TD device without first entering a password (for example, before a password entered by an operator times out).

You access the Release Password command from the main menu, as shown in figure below.

The Release Password is not applicable for the CPU password: The TD device releases the CPU password as soon as the operator exits the function that required the password.

For example: If the operator entered the CPU password in order to force an I/O point in the S7-200 CPU, the TD device releases the CPU password as soon as the operator exits the Force menu.

The Release Password command is available only if you defined a 4-digit password when you configured the TD device.

Operating Your Text Display (TD) Device 5.5 Viewing the Screens and the Alarms


Figure 5-6 Release Password Command

5.5 Viewing the Screens and the Alarms

Viewing the Screens and the Alarms As described in Chapter 4, you can configure screens and alarms for the TD device. If you configure both alarms and screens, you also designate which set of messages (screens or alarms) are the default display mode for the TD device. The default configuration selects the screens to be the default display.

After power-up or after a period of inactivity (one minute), the TD device returns to the default display mode. As shown in the figures below, the operator can switch between the default display mode and the secondary display mode.

Tip For the TD 100C, TD 200C, and the TD400C: If you do not configure buttons for ESC or ENTER, you cannot access the main menu.



Figure 5-7 TD 200, TD 200C, and TD400C - Navigating between the Default and Secondary

Displays



Figure 5-8 TD 100C - Navigating between the Default and Secondary Displays

Displaying the Alarms If you created both screens and alarms when you configured the TD device, the main menu of the TD device includes a command that allows you to access the secondary (non-default) display. The TD device always returns to the default display mode after a period of inactivity.

As shown in the TD 200C example in the figure below, the main menu provides a Display Alarms command for the default TD configuration. If you configured alarms as the default display, the main menu lists a User Menu entry.

After displaying the alarms, you use the UP and DOWN arrows to scroll through the sequential list of alarms.



Figure 5-9 Displaying the Alarms

Tip The TD 100C, TD 200C, and the TD400C allow you to configure a button specifically for displaying alarms when you are creating your custom keypad.

The TD device displays the highest priority alarm. The TD device displays an up or down arrow with the alarm to alert the operator that other alarms have been enabled. (The up arrow shows that higher-priority alarms have been enabled, and the down arrow shows that lower-priority alarms have been enabled.)

After reading a new alarm from the S7-200 CPU, the TD device sorts the alarms again to display the highest priority alarms at the top of the list. The TD device determines the priority based on the sequence of the alarms in the parameter block:

The first alarm that you created has the highest priority.

The second alarm that you created has the second-highest priority.

The last alarm that you created has the lowest priority.

Tip You can scroll up and down through the list of enabled alarms. However, the TD device returns to the highest-priority alarm after a period of inactivity: If you have not pressed a button for 10 seconds while the TD device has displayed the current alarm, then the TD device automatically returns to the highest-priority alarm.

Acknowledging an Alarm If an alarm requires acknowledgement, the TD device does not remove that alarm until you acknowledge the alarm:

1. Use the UP or DOWN arrow to select the alarm.

2. Press ENTER to acknowledge the alarm.

Types of Alarms The Text Display wizard allows you to determine the type interaction required by the operator for an alarm. If the user screens are set as the default display mode for the TD device and an alarm is enabled, an alarm indicator will begin to flash on the TD display. The indicator is large if there is an alarm enabled that requires acknowledgement. The indicator will be small if the alarms do not require acknowledgement. The user can switch to the alarm display to view the alarms.

The alarm display will show one or more alarms in priority order. An UP or DOWN arrow in the right-most character position indicates more alarms are active, but not visible on the display. The operator can press either the UP or the DOWN arrow key to scroll through the other enabled alarms.



The operator can edit or accept variable values by pressing the ENTER key. The TD device will write the updated variable value to the CPU and set the edit notification bit for that variable when the operator presses the ENTER key. The TD device then moves the cursor to the next editable variable. Pressing ENTER for the last editable variable of an alarm writes this last value to the S7-200 CPU and the TD device then resets the alarm enable bit. For more information on editing variables, see Editing a Variable that is Embedded in an Alarm or a Screen in Chapter 5.

Every alarm falls into one of four possible alarm acknowledgement and editing types. This section explains specifically how each alarm type is handled by the TD device. The four alarm types follow:

No acknowledgement required. No edits allowed

Acknowledgement required. No edits allowed

No acknowledgement required. Edits allowed

Acknowledgement required. Edits allowed

No Acknowledgement Required, No Edits Allowed In this combination of no acknowledgement required and no edits allowed, the TD device simply displays the alarm. The ENTER key has no function since there are no editable variables within the alarm. The alarm may contain variables that are updated at the update rate of the TD device. This type of alarm is replaced on the display if a higher priority alarm is enabled by the S7-200 CPU. The operator can either press the UP or the DOWN arrow key to scroll to other alarms or press ESC to return to the menus.

The TD device does not clear the corresponding alarm-enable bit in the S7-200 CPU.

Acknowledgement Required, No Edits Allowed In this combination of acknowledgement required and no edits allowed, the TD device displays the alarm and makes the entire alarm flash (blink) until the operator presses ENTER to acknowledge the alarm. Variable values are updated from the S7-200 CPU at the normal update rate while the alarm is flashing.

When the operator presses ENTER, the TD device:

Sets the acknowledgement-notification bit for this alarm.

Clears the alarm-enable bit for this alarm. This causes the alarm to be removed from the display on the next update cycle.

Another alarm cannot replace the one flashing until the operator acknowledges the flashing alarm. This is also true even if a higher priority alarm is enabled in the S7-200 CPU. If the TD device is configured for single line alarms and the CPU enables a higher priority alarm, the flashing alarm shifts down to the next line of the display. The operator cannot press the UP or the DOWN key to scroll through other enabled alarms until the current alarm is acknowledged.

No Acknowledgement Required, Edits Allowed

In this combination of no acknowledgement required and edits allowed, the TD device displays a alarm and then waits for the operator to edit a value in the alarm. All of the variables within the alarm are updated at the update rate. Since the alarm does not require acknowledgement, this type of alarm is removed from the TD device display if a higher priority alarm is enabled in the S7-200 CPU.



Acknowledgement Required, Edits Allowed

In this combination of acknowledgement required and edits allowed, the TD device displays the alarm, causes the entire alarm to flash (blink), and then waits until the operator acknowledges the alarm and edits or accepts the values in the alarm. This type of alarm requires that the operator edits or accepts the values displayed in the alarm. If the operator aborts the edit by pressing the ESC key before editing all the values in the alarm, the alarm flashes to indicate that edits are still required.

When the alarm is enabled in the S7-200 CPU, the TD device notes this and, if there is space available on the display, reads the alarm from the CPU. The TD device then displays the alarm and causes the entire alarm to flash to notify the operator that the alarm is present and must be acknowledged.

Clearing an Alarm

If an alarm required acknowledgement, the TD device will clear the alarm enable at the same time that the Alarm Acknowledgement bit is set in the CPU.

If an alarm contains editable variables, the TD device will clear the alarm enable bit when all of the edits are completed and the last editable variable in the messages is written to the CPU.

The PLC program logic may clear the alarm enable bit at any time. This will remove the alarm message from the TD display. An alarm message will not be removed from the display if the user is editing a variable in the message or if the message has not yet been acknowledged.

If the message does not require acknowledgement and/or does not contain editable variables, then the CPU program logic MUST clear the alarm enable bit.

Editing a Variable that is Embedded in an Alarm or a Screen If you configured a screen or an alarm to include a variable, you can enter a new value for the variable:

Use ENTER to move the cursor to the variable. The TD device will write the updated variable value to the CPU and set the edit notification bit for that variable when the operator presses the ENTER key, completing the edit of the variable.

Use the UP or DOWN arrows to change the value of the variable.

Use the following buttons to move the cursor to different characters within the variable:

– TD 100C, TD 200C, and TD400C: LEFT and RIGHT arrows

– TD 200: SHIFT+UP arrow and SHIFT+DOWN arrow

ESC rereads the value of the variable from the S7-200 CPU and redisplays the value.

ENTER writes the new value to the S7-200 CPU. (If the alarm contains other variables, the cursor moves to the next variable.) The TD device will write the updated variable value to the CPU and set the edit notification bit for that variable when the operator presses the ENTER key, completing the edit of the variable.

If the variable was configured as a numeric string, the cursor skips over any non-numeric characters in the message. See Chapter 4. After you have edited all of the variables in an alarm, the TD device resets the alarm bit in the S7-200 CPU.



Notice Due to restrictions in the format used to store real (floating-point) numbers in both the S7-200 CPU and the TD device, the accuracy of the number is limited to six significant digits. Editing a real number with more than six digits may not change the value of the variable, or may cause other digits within the number to change:

Changing the least significant (right-most) digit of a real-number variable with more than six digits may have no effect. For example, if you try to change the "9" in "1234.56789", the value of the variable does not change.

Changing the most significant (left-most) digit of a real-number variable with more than six digits may cause other (less significant) digits in the variable to change.



TD Bit Usage A summary of the TD bit usage is shown in Table 5-1.

Table 5- 1 Summary of TD Bit Usage

Bits Associated with Alarms and Screens

Enable Condition for the Bit

Results shown on the TD Display Clear Condition for the Bit

ALARM ENABLE The alarm must be enabled with the TD_ALRM instruction using the Alarm Symbolic Name as the instruction input.

When an alarm is enabled and the TD default display mode is set to the alarm mode, the alarm message is placed on the TD display. If there are multiple alarms enabled, the highest priority alarm is displayed. If an alarm requires user acknowledgment, the message will flash (blink) until it is acknowledged by the user. The alarm MUST be acknowledged before other alarms can be viewed. An alarm that requires acknowledgement will not be replaced on the display by higher priority alarms until the alarm is acknowledged. If the alarm contains editable variables the user can edit or accept the values (by pressing the ENTER key). If the edits are not completed, and the alarm message required acknowledgement, the message will again begin to flash. If the user screens are set as the default display mode for the TD device and an alarm is enabled, an alarm indicator will begin to flash on the TD display. The indicator is large if there is an alarm enabled that requires acknowledgement. The indicator will be small if the alarms do not require acknowledgement. The user can switch to the alarm display to view the alarms. The alarms will be presented to the user in priority order.

There are different ways to clear the alarm enable bit: If an alarm required acknowledgement, the TD device will clear the alarm enable at the same time that the 'Alarm Acknowledgement' bit is set in the CPU. If an alarm contains editable variables, the TD device will clear the alarm enable bit when all of the edits are completed and the last editable variable in the messages is written to the CPU. The PLC program logic may clear the alarm enable bit at any time. This will remove the alarm message from the TD display. An alarm message will not be removed from the display if the user is editing a variable in the message or if the message has not yet been acknowledged. If the message does not require acknowledgement and/or does not contain editable variables, then the CPU program logic MUST clear the alarm enable bit.






ALARM ACKNOW- LEDGE

Alarm acknowledgement is available only if the wizard configuration has the option enabled for this alarm: Alarm should require operator acknowledgement

The user acknowledges an alarm message by scrolling to the message and pressing the ENTER key. The TD device will then set the acknowledge notification bit in the CPU and the alarm message will stop flashing (blinking). If there are no editable variables in the message the TD device will also clear the alarm enable bit for this message. If there are editable variables in the message, the user must either edit the variables (change them and press ENTER) or accept the current values (press ENTER). When the last variable in the message is edited or accepted, the TD device will write the variable to the CPU and clear the alarm enable bit. If the user does not complete editing the variables in the message, the TD device will begin to flash (blink) the message to notify the user that an action is still pending.

The TD device will set the alarm acknowledge bit. The user program logic must clear the alarm acknowledgement bit.

Operating Your Text Display (TD) Device 5.6 Performing Typical or Routine Operator Tasks





ALARM MESSAGE: EMBEDDED VARIABLE EDIT NOTIFICATION

The edit notification is available only when the alarm contains a variable and the user has enabled the Wizard option to allow editing of the variable. "Operator is allowed to edit this data". If the alarm message contains multiple editable variables, each variable has a unique edit notification bit.

The TD device will write the updated variable value to the CPU and set the edit notification bit for that variable when the operator presses the ENTER key, completing the edit of the variable.

The user program can monitor the edit notification bit to recognize when an editable value has been changed by the operator. The user program can then take some action based on the new value for the variable. The user program must clear the edit notification bit so that subsequent edits can be recognized.

USER SCREEN: EMBEDDED VARIABLE EDIT NOTIFICATION

The edit notification is available only when the user screen contains a variable and the user has enabled the Wizard option to allow editing of the variable. "Operator is allowed to edit this data". If the user screen contains multiple editable variables, each variable has a unique edit notification bit.

The TD device will write the updated variable value to the CPU and set the edit notification bit for that variable when the operator presses the ENTER key, completing the edit of the variable.

The user program can monitor the edit notification bit to recognize when an editable value has been changed by the operator. The user program can then take some action based on the new value for the variable. The user program must clear the edit notification bit so that subsequent edits can be recognized.

(RCV) errors 1 Refer to the SIMATIC S7-200 Programmable Logic Controller System Manual for information about specific errors.

Setting Time and Date in the S7-200 CPU You can use the TD device to change the time-of-day settings in the S7-200 CPU. This allows an operator to easily adjust for time changes.

The TD device does not maintain time and date settings. In order to display the time and date values, the TD device reads the current time and date from the S7-200 CPU and displays these values. The operator can then use this screen to edit these values and then write the new time and date settings back to the S7-200 CPU.

Tip The TD device does not validate the time, date or day of the week values that you enter. You can inadvertently write an incorrect date or day of the week to the S7-200 CPU.

To allow an operator to change the time and date settings in the S7-200 CPU:

You must have enabled (selected) the time-of-day (TOD) option when you configured the TD device with the Text Display wizard. Refer to Chapter 4.

The S7-200 CPU must support the TOD clock

Tip If you configured a password for the TD device, the operator must enter the password before being allowed to set the time and date.



If the TD device was not configured to allow changes to the time or if the S7-200 CPU does not support the TOD clock, the Set Time and Date command does not appear on the Operator Menu.

After you select the Set Time command, the TD device reads the current date and time from the S7-200 CPU.

The Time and Date screen displays the following information:

Date: day-month-year (for Chinese, the date is displayed as year-month-day)

Time

Day of the week

Pressing ESC when the cursor is located on the first field of the Time and Date screen returns to the Operator Menu.



Changing the Language Set (TD 200C, TD 200, and TD400C only) You can use the TD device to change the language set in order to localize the TD device for another country. You must have created different language sets for your alarms and screens when you configured the TD device with the Text Display wizard. Each language set that you configure selects the language for the system menus and prompts of the TD device, as well as the screens and alarms. Refer to Chapter 4 for information about configuring language sets for the TD device.

Selecting the Set Language command displays a menu of the languages that you configured with the Text Display wizard as shown in the figure below. Use the UP or DOWN arrows to select the language to be displayed by the TD device.

5.7 Performing Specialized Operator Tasks (Diagnostic/Setup Menu)

Performing Specialized Operator Tasks (Diagnostic/Setup Menu) Some of the pre-configured tasks provided by the TD device provide assistance with setting up the TD device or troubleshooting problems with the S7-200 CPU. These functions are typically accessed infrequently. See the figures below.

Figure 5-15 TD 200, TD 200C, and TD400C Diagnostic Menu Hierarchy

Figure 5-16 TD 100C Diagnostic Menu Hierarchy

Tip If you are using a custom keypad that does not support the ENTER and ESC buttons, you must use the standard keypad to set up the TD device.

To restore the standard TD keypad:

1. Power down the TD device

2. Press and hold the lower right corner (where ENTER key is located on the standard keypad)

3. Power up the TD device

The default keypad is restored until the TD device is power cycled again.



Setting up the TD Device As shown in the figure below, you use the TD Setup menu to configure various parameters for the TD device, such as network addresses, address of the parameter block (stored in V memory of the S7-200 CPU), baud rate, and other communication parameters.

Setting the network address for the TD device: Use the UP or DOWN arrow to set the network address (default address = 1).

Setting the CPU address: Use the UP or DOWN arrow to select the network address for the S7-200 CPU (default = 2).

Setting the address for the parameter block: Designates a V memory location where the parameter block (or an offset to the location of the parameter block) is stored in the S7-200 CPU. Setting the address of the parameter block allows you to connect multiple TD devices to a single S7-200 CPU.

Use the UP or DOWN arrow to select the starting V memory address of the parameter block that stores the configuration of the TD device.

The address of the parameter block must match the address that you configured in the S7-200 CPU (address range: VB0 to VB32000, default = VB0).

Figure 5-17 TD Setup Menu for the TD 200 and TD 200C



Figure 5-18 TD setup menu for the TD400C

Setting the baud rate for the TD device: choose the baud rate for the TD device. You can choose either 9.6 kbaud (9600 baud), 19.2 kbaud, or 187.5 kbaud.

Use the UP or DOWN arrow to select the baud rate. The baud rate must match the baud rate of the S7-200 CPU and any other device on the same network.

Setting the Highest Station: Changes the highest station address for the TD device. This setting tells the TD device which network addresses to check when looking for other network master devices. The default highest station address is 31. This means that the TD device checks addresses 0 through 31 when looking for other network masters. This setting should only be changed when there are more than 32 master devices on the network.

Use the UP and DOWN arrows to select the highest address on the network (default = 31).

Setting the Gap Factor: Changes the Gap Factor for the TD device. This setting tells the TD device how often to check for other network master devices. The default setting of 10 causes the TD device to check once every 10 messages. A setting of 1 would cause the TD device to check for other masters after every message.

Use the UP and DOWN arrows to select the gap factor between stations (default = 10).

Setting the contrast:

– TD 100C, TD 200, and TD 200C: You can optimize the display for different viewing angles and lighting conditions by adjusting the contrast of the screen on the TD device. The default contrast value is 40, with values ranging from 25 (lighter) to 55 (darker).

Use the UP and DOWN arrows to select the contrast setting for the display area of the TD device (default setting = 40).



Selecting the keypad buzzer: The TD400C has a keypad buzzer setting (On or Off) to provide audio feedback when a key is pressed. The default is set to On.

Setting the display backlight time: The TD400C allows you to set the time that the display backlight is on allowing you to extend the life of the TD400C display.

– The backlight on time is configurable from 1 to 60 minutes in one minute increments

– You can configure the backlight to be on all the time

– The default backlight on time is 10 minutes

Tip At 9600 baud or 19.2 kbaud, the highest station address may need to be increased, even though the network does not contain more than 32 masters. Increasing the highest station address allows more time for the masters to transmit messages.

Viewing the TD Messages Stored in the S7-200 CPU (TD 200, TD 200C, and TD400C only) You can review all of the TD messages (screens and alarms) that you configured for the TD device within the language set currently selected for the TD device.

The View Messages command allows you to verify that all of the alarms and screens were correctly stored in the S7-200 CPU.

The View Messages command does not allow you to edit any values that are displayed in the messages.

Selecting the View Messages command displays all of the messages and process values stored in the S7-200 CPU. Use the UP and DOWN arrows to scroll through messages stored in the S7-200 CPU.

Figure 5-19 View Messages Command

Forcing the Inputs and Outputs in the S7-200 CPU (TD 200, TD 200C, and TD400C only) The Force I/O menu allows you to force inputs, force outputs, or unforce all inputs and outputs. The Force I/O command is available only if you enabled the force-menu when you configured the TD device with the Text Display wizard.

Caution Turning off the power to the S7-200 CPU before the force information is written to the permanent memory in the CPU can cause the S7-200 CPU to experience a failure the next time you turn the S7-200 CPU on.



To clear the error condition, use the TD device to either unforce all of the I/O points or else rewrite the force information to the S7-200 CPU. Cycling the power to the S7-200 CPU should clear the error.

If the S7-200 CPU requires a password before allowing the I/O to be forced, the TD device prompts the operator to enter the 8-character CPU password.

The Force I/O command provides the following options:

Force Inputs: Allows you to force individual inputs on or off, or to turn off the Force function

Force Outputs: Allows you to force individual outputs on or off, or to turn off the Force function

Unforce All I/O: Allows you to turn off the Force function for all of the forced I/O points

Use the UP or DOWN arrow to select the specific I/O point. Pressing ENTER moves the cursor to the Force options. (For a TD 200C and TD400C, you can also use the RIGHT arrow. For a TD 200, you can use the SHIFT+DOWN arrow.)

Use the UP or DOWN arrow to select the type of force condition for the selected I/O point.

Figure 5-20 Force I/O Command

Tip Unforcing the I/O points does not place them in the OFF state. Unforcing only removes the Force option. The points remain in their last state until you manually change them or they are changed by the user program in the S7-200 CPU.

Changing the Operating Mode of the S7-200 CPU (TD 200C and TD400C) The Change STOP/RUN Mode command is only available for the TD 200C and TD400C and is only available if you selected this function when you configured the TD device with the Text Display wizard. See Chapter 4.

You can use the TD device to change the operating mode of the S7-200 CPU from STOP to RUN or from RUN to STOP. The operator may need to enter the TD password, if the TD device is configured for password-protection.



In order to allow the TD device to change the operating mode, the mode selector switch on the S7-200 must be set to either RUN or TERM.

The TD device cannot change the operating mode if the mode selector switch is set to STOP.

A.9 Simplified Chinese Character Set

Simplified Chinese Character Set The TD devices support the Simplified Chinese character set (GB2312-80) for the People's Republic of China. The TD devices use Microsoft Windows encoding for this character set. The Windows encoding allows the TD devices to display the same characters as shown in the STEP 7-Micro/WIN Text Display wizard when you are using a Chinese emulator or a Chinese version of Microsoft Windows.

Chinese characters are represented in STEP 7-Micro/WIN by a pair of numbers which represent the encoding of the character in the GB2312-80 specification. The TD devices also use a pair of numbers to represent the Chinese character.

Notes for Using the Simplified Chinese Character Set Tip The Simplified Chinese character set requires a Chinese version of Windows or a Chinese emulator to properly display Chinese characters in the Text Display wizard. You must start the Chinese emulator before you start the STEP 7-Micro/WIN software.

On the TD 200C and the TD 200, you can display up to 20 single-byte characters per line of your message. Because Simplified Chinese uses double-byte characters, you can display up to 10 double-byte characters per line for a message in Chinese.

On the TD 100C, you can display up to 16 single-byte characters per line of your message. Because Simplified Chinese uses double-byte characters, you can display up to 8 double-byte characters per line for a message in Chinese.

On the TD400C using a small font, you can display up to 24 single-byte characters per line of your message. Because Simplified Chinese uses double-byte characters, you can display up to 12 double-byte characters per line for a message in Chinese. If you selected a large font, you can display up to 16 single-byte characters or 8 Chinese characters.

The standard ASCII characters, such as numbers, punctuation, and upper and lowercase alphabet characters, are available when using the Simplified Chinese character set (shown below). Depending on your keyboard and/ or emulator, some of these standard characters may be formatted as single-byte characters instead of the double-byte characters like the Simplified Chinese characters. Standard ASCII characters and Chinese characters can be mixed on the TD display.

The Text Display wizard displays 8 , 10, or 12 double-byte character places for the text of a screen or alarm. You can fit any of the following combinations into a character position:

1 double-byte character

2 single-byte characters (standard ASCII)

1 single-byte character and 1 single-byte blank

You cannot fit one single-byte character plus one double-byte character in a character position.

Technical Specifications and Reference Information A.9 Simplified Chinese Character Set


TD 100C does not support the entire Simplified Chinese character set, however, the most-used characters have been included in the TD 100C. See the Simplified Chinese Characters Set for a list of supported characters. Characters that are not supported by the TD 100C are displayed as a square.

Tip The Simplified Chinese Character Set electronic file resides on the STEP 7-Micro/WIN documentation CD. This file shows the characters supported by the different TD devices.

Connecting Multiple Devices on a Network BB.1 Overview

Overview of Appendix B You can connect multiple TD devices and S7-200 CPUs together on one communication network. The TD devices act as network masters and do not interfere with each other. You can designate the S7-200 CPUs to be either masters or slaves on the network.

B.2 Communicating with Multiple CPUs

Communicating with Multiple CPUs Figure B-1 shows a typical network with two TD 200s and two S7-200 CPUs. Each TD 200 communicates to one of the CPUs. The addresses of each device are noted below the device in the figure. In this example:

TD 200 Number 1 is configured to communicate to the S7-200 CPU at address 2 (CPU 1)

TD 200 Number 2 is configured to communicate to the S7-200 CPU at address 3 (CPU 2)

Tip You can connect multiple TD devices to a single S7-200 CPU. You can store separate parameter blocks for each TD device in different V memory locations in the CPU.

If you do not store separate parameter blocks for each TD device that is connected to the CPU, any of these TD devices can acknowledge the same messages and use function keys to initiate operations in the CPU.

Figure B-1 Typical Multiple CPU Network

Connecting Multiple Devices on a Network B.3 Determining the Distances, Transmission Rate, and Cable


Tip The display time slows as more TD devices are added to the network.

Network connectors are available from Siemens. Using these connectors allows you to isolate the CPUs from one another (the 24 VDC), but still allows you to power the TD device from the CPU. See the SIMATIC S7-200 Programmable Controller System Manual for more information about using network connectors.

B.3 Determining the Distances, Transmission Rate, and Cable

Determining the Distances, Transmission Rate, and Cable As shown in Table B-1, the maximum length of a network segment is determined by two factors: isolation (using an RS-485 repeater) and baud rate.

Isolation is required when you connect devices at different ground potentials. Different ground potentials can exist when grounds are physically separated by a long distance. Even over short distances, load currents of heavy machinery can cause a difference in ground potential.

Table B- 1 Maximum Length for a Network Cable

Baud Rate Non-Isolated CPU Port1 CPU Port with Repeater or EM 277 9.6 kbaud to 187.5 kbaud 50 m 1,000 m 1 The maximum distance allowed without using an isolator or repeater is 50 m. You measure this distance from the first node to the last node in the segment,

Using Repeaters on the Network An RS-485 repeater provides bias and termination for the network segment. You can use a repeater for the following purposes:

To increase the length of a network: Adding a repeater to your network allows you to extend the network another 50 m. If you connect two repeaters with no other nodes in between (as shown in Figure B-2), you can extend the network to the maximum cable length for the baud rate. You can use up to 9 repeaters in series on a network, but the total length of the network must not exceed 9600 m.

To add devices to a network: Each segment can have a maximum of 32 devices connected up to 50 m at 9600 baud. Using a repeater allows you to add another segment (32 devices) to the network.

To electrically isolate different network segments: Isolating the network improves the quality of the transmission by separating the network segments which might be at different ground potentials.

A repeater on your network counts as one of the nodes on a segment, even though it is not assigned a network address.

Connecting Multiple Devices on a Network B.4 Selecting the Network Cable


Figure B-2 Sample Network with Repeaters

B.4 Selecting the Network Cable

Selecting the Network Cable S7-200 networks use the RS-485 standard on twisted pair cables. Table B-2 lists the specifications for the network cable. You can connect up to 32 devices on a network segment.

Table B- 2 General Specifications for Network Cable

Specifications Description Cable type Shielded, twisted pair Loop resistance ≤115 Ω /km Effective capacitance 30 pF/m Nominal impedance Approximately 135 Ω to 160 Ω (frequency =3 MHz to 20 MHz) Attenuation 0.9 dB/100 m (frequency=200 kHz) Cross-sectional core area 0.3 mm2 to 0.5 mm2 Cable diameter 8 mm ±0.5 mm

B.5 Biasing and Terminating the Network Cable

Biasing and Terminating the Network Cable Siemens provides two types of network connectors that you can use to easily connect multiple devices to a network: a standard network connector and a connector that includes a programming port (which allows you to connect a programming station or an HMI device to the network without disturbing any existing network connections). The programming port connector passes all signals (including the power pins) from the S7-200 through to the programming port, which is especially useful for connecting devices that draw power from the S7-200 (such as a TD 200).

Both connectors have two sets of terminal screws to allow you to attach the incoming and outgoing network cables. Both connectors also have switches to bias and terminate the network selectively. Figure B-3 shows typical biasing and termination for the cable connectors.

Figure B-3 Bias and Termination of the Network Cable

B.6 Building a TD/CPU Cable

Building a TD/CPU Cable The TD/CPU cable is used for connecting a display device to an S7-200 CPU. If you do not have a TD/CPU cable, refer to Figures B-4 and B-5 to create your own cable.

Making a Cable That Supplies Power to the TD Device

CAUTION Connecting the 24 VDC power output (pin 7 of communication port) of multiple S7-200 CPUs may cause erratic operation of the I/O, which could potentially cause personal injury and/or property damage.

The 24 VDC power supply is also the sensor supply for the I/O. Interconnecting the output power supplies of multiple CPUs could possibly overload the sensor supply, which could cause the I/O to operate incorrectly.

When networking S7-200 CPUs, connect only the communication lines (pins 3, 5, and 8). You must not connect the power output (pin 7).

Tip The TD 100C must use the TD/CPU cable shown in Figure B-4.

Connecting Multiple Devices on a Network B.6 Building a TD/CPU Cable


Figure B-4 shows you the pin-out of TD/CPU cable with power supplied to the TD device. Use this option when you want the TD device to receive power from an S7-200 CPU.

Figure B-4 TD/CPU Cable with Power Connections

Making a Cable That Does Not Supply Power to the TD Device (TD 200, TD 200C, and TD400C only) Figure B-5 shows you the pin-out of a TD/CPU cable without power supplied to the TD device. Use this option when you want the TD device to receive power from an external power supply. The maximum length for the cable is 1200 meters.

Connecting Multiple Devices on a Network B.7 CPU Grounding and Circuit Reference Point Guidelines for Using Isolated Circuits


B.7 CPU Grounding and Circuit Reference Point Guidelines for Using Isolated Circuits

CPU Grounding and Circuit reference Point Guidelines for Using Isolated Circuits The following items are CPU grounding and circuit guidelines for using isolated circuits:

You should identify the reference point (0 voltage reference) for each circuit in the installation, and the points at which circuits with possibly different references can connect together. Such connections can result in unwanted current flows that can cause logic errors or can damage circuits. A common cause of different reference potentials is grounds that are physically separated by long distances. When devices with widely separated grounds are connected with a communication or sensor cable, unexpected currents can flow through the circuit created by the cable and the ground. Even over short distances, load currents of heavy machinery can cause differences in ground potential or can directly induce unwanted currents by electromagnetic induction. Power supplies that are improperly referenced with respect to each other can cause damaging currents to flow between their associated circuits.

When you connect CPUs with different ground potentials to the same PPI network, you should use an isolated RS-485 repeater.

S7-200 products include isolation boundaries at certain points to help prevent unwanted current flows in your installation. When you plan your installation, you should consider where these isolation boundaries are provided, and where they are not provided. You should also consider the isolation boundaries in associated power supplies and other equipment, and where all associated power supplies have their reference points.

You should choose your ground reference points and use the isolation boundaries provided to interrupt unneeded circuit loops that could allow unwanted currents to flow. Remember to consider temporary connections which may introduce a new circuit reference, such as the connection of a programming device to the CPU.

When locating grounds, you must also consider safety grounding requirements and the proper operation of protective interrupting devices.

In most installations, you will have the best noise immunity if you connect the CPU sensor supply M terminal to ground.

The following descriptions are an introduction to general isolation characteristics of the S7-200 family, but some features may be different on specific products. Consult your product specifications in the appropriate manual for information about which circuits include isolation boundaries and the ratings of the boundaries. Isolation boundaries rated less than 1,500 VAC are designed as functional isolation only, and should not be depended on as safety boundaries.

Logic circuit reference is the same as DC sensor supply M.

Logic circuit reference is the same as the input power supply M on a CPU with DC power supply.

CPU communication ports have the same reference as logic circuit.

Analog inputs and outputs are not isolated from logic circuit. Analog inputs are full differential to provide low voltage common mode rejection.

Logic circuit is isolated from ground to 500 VAC.



DC digital inputs and outputs are isolated from logic circuit to 500 VAC.

DC digital I/O groups are isolated from each other by 500 VAC.

Relay outputs are isolated from logic circuit to 1,500 VAC.

Relay output groups are isolated from each other by 1,500 VAC.

AC power supply line and neutral are isolated from ground, the logic circuit, and all I/O to 1,500 VAC.
